CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. 119 of the earlier filing date of U.S. Provisional Application No. 62/037,616 entitled “CANAL HEARING DEVICE AND METHODS FOR WIRELESS REMOTE CONTROL OF AN APPLIANCE,” filed Aug. 15, 2014. The aforementioned provisional application is hereby incorporated by reference in its entirety, for any purpose.

TECHNICAL FIELD

Examples described herein relate to hearing devices, and include particularly canal hearing devices including wireless capabilities for actuation or control of an appliance in proximity.

BACKGROUND

The ear canal 10, as illustrated in FIG. 1, is generally narrow and tortuous, and is approximately 26 millimeters (mm) long from the canal aperture 11 to the tympanic membrane 15 (eardrum). The lateral part of the ear canal 10 is referred to as the cartilaginous region 12 due to the underlying cartilaginous tissue 16 beneath the skin. The medial part, proximal to the tympanic membrane 15, is relatively rigid and referred to as the bony region 13 due to the underlying bone tissue 17. A characteristic first bend occurs roughly at the aperture 11 (FIG. 1) of the ear canal 10. The concha cavity 5 is just outside the ear canal 10 behind the tragus 3. A second characteristic bend occurs roughly at the bony-cartilaginous junction 8 and separates the cartilaginous region 12 and the bony region 13. The two bends inside the ear canal 10 define a characteristic “S” shape. Just outside the ear canal 10 is the concha cavity 5, which is hidden behind a backward projecting eminence known as the tragus 3. The ear canal 10 and concha cavity 5 are generally hidden from view from the front and side by the presence of the tragus 3, and also hidden from the back by the presence of the pinna (also referred to as auricle). Therefore, placement of a hearing device inside the concha cavity 5 and into the ear canal 10 is highly advantageous for highly inconspicuous wear. The dimensions and contours of the ear canal 10 vary significantly among individuals.

Placement of a canal hearing device inside the ear can be challenging due to difficulty in access and manipulation of a miniature canal device, particularly when placed deeply inside the ear canal 10. However, it is generally desirable to place a hearing device inside the ear canal 10 for achieving various advantages including reduction of the acoustic occlusion effect, improved energy efficiency, reduced distortion, reduced receiver (speaker) vibrations, and improved high frequency response. A well-known advantage of ear canal 10 placement is aesthetics as many hearing-impaired individuals refuse to wear visible hearing devices such as in-the-ear (ITE) or behind-the-ear (BTE) types.

Placement of a hearing device inside the ear canal 10 is generally desirable for various electroacoustic advantages such as reduction of the acoustic occlusion effect, improved energy efficiency, reduced distortion, reduced receiver vibrations, and improved high frequency response. A canal hearing device can be inserted entirely or partially inside the ear canal. In the context of this application, any hearing device inserted inside the ear canal, whether partially or completely, may be referred to as a canal hearing device. This includes what is known in the hearing aid industry as Completely-In-The-Canal (CIC) and In-The-Canal (ITC) types.

Switches placed on canal hearing devices are generally difficult to reach or activate. These switches may be cumbersome if not impossible for those with dexterity limitations. Switches for hearing devices are generally implemented for larger hearing devices such as BTEs and ITEs for access and manual manipulation to deal with dexterity limitations.

Current hearing devices include wireless capabilities to receive transmit a variety of signals. The signals may include telephony audio, consumer electronics audio, and/or programming signals. In some examples, hearing devices connect to a computing device such as a mobile device or a personal computer to receive the wireless signals. In some examples, wireless hearing devices connect with an intermediary device that receives wireless signals from a source device external to the hearing device and re-transmits or relays the signal to the hearing device in proximity to the intermediary device.

SUMMARY

A hearing system may include a canal hearing device and a computing device. The canal hearing device may include a medial portion, a lateral portion, and wireless electronics. In some examples, the canal hearing device may be modular. The medial portion may include a speaker. The medial portion may be configured for placement inside an ear canal of an ear. In some examples, the medial portion may include a sound processor configured to generate an audible signal. The speaker may be configured to provide the audible signal inside the ear canal.

The lateral portion may include a wireless antenna and a switch. In some examples, the lateral portion may include a battery cell. The switch may be arranged on the lateral portion such that the switch is located in a concha cavity of the ear when the medial portion is placed inside the ear canal. The switch may be positioned behind a tragus of the ear. The switch may be configured for manual activation. In some examples, the lateral portion may include a handle portion and the switch may be on the handle portion.

The wireless electronics may be communicatively coupled to the wireless antenna. The wireless electronics may be configured to transmit a wireless signal to the external appliance via the wireless antenna when the external appliance is within proximity to the canal hearing device and responsive to manual activation of the switch. In some examples, the wireless signal may be configured to control any of an electronic lock, an electronic lighting, a telephone, a medical alert system, a television, a medical device, and electronic glass. The canal hearing device may produce an audible sound from the speaker when the canal hearing device is worn in the ear and in proximity to the external appliance. The audible sound may be produced in response to receiving a wireless signal from the external appliance. The canal hearing device may terminate production of the audible sound in response to a manual activation of the switch.

The computing device may be separate from the canal hearing device. The computing device may be communicatively coupled to the canal hearing device. The canal hearing device may receive configuration parameters from the computing device. The canal hearing device may include memory for storing the configuration parameters. The canal hearing device may control the external appliance in accordance with the configuration parameters.

DETAILED DESCRIPTION

Certain details are set forth below to provide a sufficient understanding of embodiments of the invention. However, it will be appreciated by one skilled in the art that some embodiments may not include all details described. In some instances, well-known structures, hearing aid components, circuits, and controls, have not been shown in order to avoid unnecessarily obscuring the described embodiments of the invention.

The present disclosure describes examples of systems and methods of wireless remote control of appliances using a canal hearing device in proximity thereto. One embodiment of the present disclosure involves a canal hearing device including a switch for manual activation. In some examples, the canal hearing device may control an appliance external to the ear upon manual activation of the switch.

FIGS. 2 and 3 show examples of a canal hearing device 100, according to the present disclosure. The canal hearing device 100 may include a medial end 106 (also referred to herein as “medial portion”), a lateral end 102 (also referred to herein as “lateral portion”), a compliant sealing retainer 108. The canal hearing device may include wireless electronics 116 (e.g., as illustrated in FIG. 9). The lateral end 102 may be coupled electrically and mechanically to the medial end 106 for operation of the canal hearing device 100 in the ear. In some examples, the medial end 106 may be integrated with the lateral end 102. In some examples, the canal hearing device may be a modular canal hearing device 100 which includes a medial end 106 (also referred to herein as “main module”) and a lateral end 102 (also referred to herein as “lateral module”) removably coupled to the lateral end 102. The lateral end 102 may be detachable from the medial end 106, for example for replacement of a battery cell which may be received, at least partially, within the lateral end 102. In some examples, the lateral end 102 may include a detachable and/or disposable battery module. The medial end 106 may be configured to at least partially disengage from the lateral end 102, e.g., as illustrated in FIG. 3 where the medial end 106 is shown detached from the lateral end 102. Partial disengagement may provide the canal hearing device 100 in an OFF condition. Full disengagement may be advantageous for example canal hearing devices with a replaceable lateral end 102. Engagement between the medial end 106 and lateral end 102 may provide the canal hearing device 100 in an ON condition. The canal hearing device 100 may be sized and shaped for placement substantially inside the ear canal 10 and extending to the concha cavity 5 behind the tragus 3. The medial end 106 may be placed inside an ear canal 10. The canal hearing device 100 (FIG. 10) may include any of a speaker 124, a microphone 122, a sound processor 126, memory 128 and circuitry.

The lateral end 102 may be positioned lateral to (away from the eardrum 15) and may include a battery portion 101 and a handle portion 104 (also referred to herein as “handle”) for placement in the concha cavity 5 behind the tragus 3. The lateral end 102 may include one or more switches, a wireless antenna, and a battery cell. The lateral end 102 may be removable, partially disengageable, or integral with the medial end 106. The lateral end 102 may further include a sound port and sound channel for receiving incoming sound, for example as described in U.S. Pat. No. 8,467,556, titled CANAL HEARING DEVICE WITH DISPOSABLE BATTERY MODULE (“'556 patent”), and U.S. Pat. No. 8,855,345, titled BATTERY MODULE FOR PERPENDICULAR DOCKING INTO A CANAL HEARING DEVICE (“'345 patent”), which are both incorporated herein by reference in their entirety for any purpose. In some examples, the compliant sealing retainer 108 may be removably coupled to the medial end 106 and configured to retain the medial end 106 in the ear canal 10. In some examples, the compliant sealing retainer 108 may be removable and provided in an assortment of sizes to fit in a variety of ear canal shapes and sizes.

The lateral end 102 may include one or more switches that may be activated in response to a manual force. In some examples, the one or more switches may be provided on the handle 104 of the canal hearing device. In some examples, the one or more switches may be provided on a housing of the lateral end 102, such as on the side of the housing (FIG. 7). In some examples, a first switch 114 may be activated indirectly by a manual force applied to a tragus 3. In some examples, the first switch 114 may be arranged on the lateral end 102 such that the first switch 114 is oriented towards the tragus 3 when the medial portion 106 is placed inside the ear canal. In this manner, the application of manual force to the tragus 3 may cause the tragus 3 to contact the first switch 114 thereby activating the first switch 114. In some examples, a second switch 110 may be activated by a manual force directly applied to a first area of the handle 104. In some examples, a third switch 112 may be activated by a manual force directly applied to a second area of the handle 104. Any of the one or more switches may be arranged on the lateral end 102 of the canal hearing device such that one or more of the switches are located in the concha cavity 5. In this manner, one or more of the switches may be generally hidden behind the tragus 3 (FIG. 6) for conspicuous wear of the canal hearing device in the ear. The one or more switches may include a button switch (FIGS. 2-3 and 7-8), a rocker switch 502 (FIG. 4), a proximity sensor switch (not shown), a capacitive switch (not shown), and/or other known switches suitable for manual activation.

In some examples, the one or more switches may be implemented as a rocker switch 502 on a handle 500 of the canal hearing device 100, as shown in FIG. 4. The rocker switch 502 may include two switches each configured to be manually activated. The two switches may include a first switch 504 located at a first end of the rocker switch 502 and a second switch 506 located at a second end of the rocker switch 502. Manual manipulation of either of the first or second end of the rocker switch (e.g., a pressure applied to the first end or the second end) may cause activation of the respective switch located at that end. In some examples, any of the switches may be positioned such that they may be reached by a finger 9 of a user 1, as shown in FIGS. 6 and 11. Alternatively, a switch 700 may be provided on a side of the lateral end 102 such that the switch 700 is behind the tragus 3 when the medial end 106 of the canal hearing device 100 is positioned in the ear canal 10, as shown in FIG. 8. In some examples, the user 1 may apply a manual force to the tragus 3 using a finger 9 to activate the switch. In some examples, the user 1 may apply a manual force to the tragus 3 using a tool to activate the switch.

The lateral end 102 may include a wireless antenna. In some examples, the wireless antenna may be a chip antenna, for example a ceramic chip antenna. The wireless antenna may be communicatively coupled to wireless electronics 116 of the canal hearing device 100. The wireless electronics 116 may be provided in any of the medial end 106 or the lateral end 102. The wireless electronics 116 may include functionality to transmit and receive wireless signals. The wireless electronics 116 may utilize standardized protocols, such as Bluetooth, near-field magnetic induction, Wi-Fi, Zigbee or any other known wireless protocol. In some examples, the wireless electronics 116 include low power and low energy functionalities compatible with miniature button cell or coin cell batteries that are commonly used for hearing aids and miniature electronic devices. Bluetooth, including Low Energy (LE) versions, is particularly suited.

The wireless electronics 116 may communicate wirelessly with an appliance 800 (FIG. 5) external to the ear. The appliance 800 external to the ear may interchangeably be referred to herein as external appliance 800. The appliance 800 may be any device with wireless capability, for example an electronic lock (e.g., electronic door lock), a thermostat, electronic lighting (e.g., electronic room lighting), a telephone, a kitchen appliance, a medical alert system, a television, a medical device including an electronic medicine dispensing bottle, or a smart glass (also referred to herein as “electronic glass”). The appliance 800 may include wireless electronics 808 for communicatively coupling with the canal hearing device 100 and receiving control signals therefrom. An appliance controller 806 of the appliance 800 may provide access to configuration data including control parameters such as ON/OFF, Open/Close, Up/Down (e.g., volume), and Increase/Decrease (e.g., temperature). Typically, these control parameters are controlled by switches on the appliance 800 itself, or by an external remote control. More recently, appliance operating systems 814 may include functionality for wireless control by a Smartphone and a control software application 910. In some examples, the switches of the canal hearing device 100 may include an electromechanical type, a capacitive touch type, or optical sensor. When the appliance 800 is out of reach of the user 1, an external remote control device or a Smartphone may be used to control the appliance 800. Examples disclosed herein may mitigate the need to rely on inaccessible devices and methods for the remote control of an appliance 800 by using the canal hearing device 100 to control the appliance 800 (e.g., to operate controls of the appliance and/or activate the appliance 800).

The wireless electronics 116 of the canal hearing device 100 may communicatively couple with wireless electronics 808 of the appliance 800 to transmit and receive wireless signals 802. The wireless signals 802 may include commands, audio, and/or any other type of data. In some examples, the wireless electronics 116 of the canal hearing device 100 may transmit a wireless signal 802 in response to the manual activation of any of the one or more switches of the canal hearing device 100. The wireless signal 802 may include a signal configured to control the appliance 800. The wireless signal 802 may be received by the appliance 800, and a processor 804 of the appliance 800 may be in communication with the appliance controller 806 and an appliance operating system 814 to control the appliance 800. The appliance 800 may include memory 810 for storing appliance configuration data and the appliance operating system 814. The appliance configuration data may include control parameters for control and/or actuation of the appliance 800 in response to receiving the wireless signal 802. Thus, the user 1 may apply a manual force to the tragus 3 and/or directly to any of the switches 110-114 of the canal hearing device 100 to control the appliance 800. The actuation and/or control of the appliance 800 may include adjustment of the appliance 800 as discussed above, such as manipulating a light or lock. This may be advantageous to use a canal hearing device 100 as a remote control to mitigate the need for an external remote device such as a mobile phone.

In some examples, the canal hearing device 100 may automatically detect the presence of an external appliance 800 in proximity. In other words, the canal hearing device 100 may be configured to automatically detect the external appliance 800 when the external appliance 800 is within a wireless detection range. The appliance 800 may be in sufficient proximity to the canal hearing device 100 such that a wireless signal may be received from and/or transmitted to the canal hearing device 100 from the appliance 800. It will be appreciated that the distance defining proximity depends on the wireless capability of the canal hearing device 100 and the wireless protocol. For example, proximity may be 2-10 meters for low energy Bluetooth. In some examples, proximity may be a greater distance than the direct wireless capability of the canal hearing device 100 by using a mesh network. In some examples, the wireless electronics 116 may periodically scan for the presence of an appliance 800, or respond to a scan from the appliance 800. In some examples, the wireless electronics 116 may perform a scan in response to a manual activation of a switch 110-114. The canal hearing device 100 may access appliance control parameters 130 associated with the detected appliance 800 and configuration data 132 from memory 128 of the canal hearing device 100. The appliance control parameters 130 determine the pre-selected control method associated with the appliance 800 and/or switch mapping for the appliance 800 (e.g., which switch performs which command). The configuration data 132 may include personal user settings, personal fitting parameters, appliance preferences, etc. For example, the configuration data 132 may include appliance preferences ranking appliances based on usage or user preference, automatic control settings of an appliance 800 (e.g., automatic door unlock), and/or alert settings for an appliance 800.

In some examples, the canal hearing device 100 may be configured to produce an audible sound (also referred to herein as “audible signal”) from the speaker 124 when the canal hearing device 100 is worn in the ear and in proximity to the appliance 800. In some examples, the canal hearing device 100 includes a speaker 124 in the medial portion 106 to deliver audible signals 120 in the ear canal 10. The audible signal 120 may be representative of the audio signal streamed from the appliance 800 or internally generated by the canal hearing device 100 to play a particular audio segment related to the presence or control of the appliance 800. In some examples, audio data 134 associated with the audio segment may be stored in memory 128 of the canal hearing device 100. The audio data stored in memory 128 may be accessed and played back using the sound processor 126 within the canal hearing device 100 in response to the detection, or from the activation or control of the appliance 800 due to hearing device switch activation. The production of the audible signal 120 may be terminated by manually activating any switch of the canal hearing device 100.

In some examples, the canal hearing device 100 may automatically detect the presence of the appliance 800. In response to detection of the appliance 800, the canal hearing device 100 may deliver an appropriate audible signal 120 (e.g., an audible segment) to a user 1 wearing the canal hearing device 100. The audible signal 120 may be produced through the speaker 124. This audible signal 120 may alert the user 1 to the presence of the appliance 800 in proximity and allow the user 1 to wirelessly control the appliance 800 detected in proximity to the canal hearing device 100. In some examples, control of the appliance 800 is automatic. Thus, the one or more switches of the canal hearing device 100 may not be required to control the appliance 800. The canal hearing device 100 may detect the presence of an appliance 800 in proximity to the canal hearing device 100 and control the appliance 800 based on appliance control parameters 130 and configuration data 132 (collectively referred to herein as “configuration parameters”) stored within memory 128 of the canal hearing device 100. For example, the canal hearing device 100 may detect the presence of a lock and in response to detecting the lock, the canal hearing device 100 may wirelessly transmit a secure open-door command signal to unlock a door for entry. This may be advantageous to provide a hands-free home entry for a user 1. In other examples, the open-door command is delivered upon activation of a hearing device switch positioned in the concha cavity 5 behind the tragus 3 according to the examples of the present disclosure.

In some examples, upon detection of the appliance 800 in proximity, the canal hearing device 100 may retrieve appliance status data of the appliance 800, for example whether a door is locked or unlocked, or whether the appliance is on or off. The canal hearing device 100 may deliver a wireless control signal to the appliance based on the appliance status data. For example, the canal hearing device 100 may deliver a wireless control signal to unlock the door only when the appliance status data indicates that the door is locked and will not perform any action if the door is already unlocked. In some examples, the canal hearing device 100 may detect whether the appliance 100 is getting closer or further away when in proximity range, for example when the user 1 is approaching a door or moving away from the door, and send a wireless control signal based on the movement direction of the user 1 with respect to the appliance 800. For example, the canal hearing device 100 may unlock a door that the user 1 is approaching and/or lock a door that the user 1 is moving away.

The canal hearing device 100 may be communicatively coupled to a computing device 900 over a wireless interface. In some examples, the canal hearing device 100 may be programmed by the computing device 900, such as a personal computer, a Smartphone, or a tablet. The computing device 900 may include memory 904 for storing control software application 910 for adjusting appliance control parameters 130 and/or configuration data 132 of the canal hearing device 100. For example, the functionality of the switches 110-114 may be customized using the control software application 910. The control software application 910 may executable by a processor 906 of the computing device 900 to send control signals 902 to the canal hearing device 100 for setting the appliance control parameters 130 of the canal hearing device 100. The control software application 910 may be configured to send and receive control signals 902 to and from the canal hearing device 100, such as the appliance control parameters 130, configuration data 132, and/or other status information of the canal hearing device 100.

In some examples, a binaural set of hearing devices may be configured differently and independently for the control of the same of multiple appliances. A first canal hearing device of a binaural set may be configured for controlling a light and a second canal hearing device may be configured for controlling a television. One switch of the first canal hearing device may be configured for actuation of appliances (e.g., On/Off for a TV or lighting), while the switches of the second canal hearing device may be configured to change the settings of the appliances, for example changing the volume, channel, dimming, or other settings.

In some examples, the canal hearing device 100 may include telephony functionalities via wireless connectivity to a telephone. A first switch of the canal hearing device 100 may be manually activated to answer an incoming call. The canal hearing device 100 may deliver a telephone audio signal to the ear canal 10 of the user using the speaker 124 of the canal hearing device 100 in response to the activation of the switch to answer the phone call. A second or the same switch of the canal hearing device 100 may be manually activated to adjust the volume of the telephone audio signal in the ear upon taking the incoming call.

The canal hearing device 100 may store audio data 132 that may be played back using the sound processor 126 and speaker 124 of the canal hearing device 100 to alert the user to an incoming call or message. The alert may be a stored audio segment or may be provided to the canal hearing device 100 wirelessly during the incoming call, for example to include the name of the caller in the alert. The audio data 132 may include voice messages or voice memos. The audio data 132 may include text messages converted to audio messages, such as from e-mail, SMS, social media posts, and/or other text-based messages. The computing device 900, for example a smartphone, may provide the canal hearing device 100 with voice messages, voice memos, and/or text messages converted to audio messages. The canal hearing device 100 may include an interface for presenting stored audio data 132 to the user 1, such as by listing the stored messages and allowing the user 1 to scroll and select the one(s) they wish to play back using the switches 110-114.

In some examples, the appliance 800 may be a medical device. The canal hearing device 100 may detect the presence of the medical device. Upon detection of the medical device or by a command from the medical device, the canal hearing device 100 may deliver an audio signal to the ear canal 10 of the user. The canal hearing device 100 may receive alerts related to medical or health events from the medical device. The canal hearing device 100 may present the alerts to the user 1 by delivering an audio signal to the ear canal 10 of the user 1. In response to a manual activation of a switch of the canal hearing device 100, the canal hearing device 100 may transmit a wireless signal to the medical device for acknowledgment, control or verification. For example, the canal hearing device 100 may communicate wirelessly with an electronic medicine dispenser bottle (referred to herein as “e-dispenser”) housing one or more medications (pills, for example) and provide an audible signal as a reminder for the user 1 to take any of the medications upon a wireless request from the e-dispenser. The user 1 may disable or terminate the repeating audio messages by activating a switch on the canal hearing device 100 which may also trigger a wireless confirmation signal to the e-dispenser. The e-dispenser through its processor may perform a verification of taking the medication, for example by ensuring that the user 1 actually opened the bottle during an appropriate time frame. If verification is negative, the e-dispenser may continue to request the canal hearing device 100 to generate an audible reminder signal through the speaker 124 of the canal hearing device 100.

By placing the canal hearing device 100 in the ear canal 10 and extending laterally to the concha cavity 5 behind the tragus 3, the canal hearing device 100 is generally inconspicuously and securely worn within the ear, allowing for normal daily activity including running, hunting, sports and exercising in general. Additionally, the switches of the canal hearing device 100 are configured to be readily accessible to the user 1, e.g., to enable transmission of wireless signals to a variety of appliances, thereby allowing control of other devices used and encountered frequently in daily life.

In some examples, the canal hearing device 100 may be water-proof or water-resistant so as to allow for showering and swimming while the canal hearing device 100 is worn inside the ear canal 10 and behind the tragus 3. The inconspicuous wear of the canal hearing device 100 worn generally behind the tragus 3 disclosed herein allows for discrete and private communications without alerting others. In contrast, existing Bluetooth-enabled hearing devices extend outside the concha cavity 5, including behind the ear, and compromise secure and inconspicuous wear.

FIGS. 12-13 are flow charts of methods one or both of which may be embodied in a canal hearing device and/or a hearing system according to some examples of the present disclosure. While the various steps in these flowcharts are presented and described sequentially, one of ordinary skill will appreciate that some or all of the steps can be executed in different orders and some or all of the steps can be executed in parallel. Further, in some examples, one or more of the steps described below can be omitted, repeated, and/or performed in a different order. Accordingly, the specific arrangement of steps shown in FIGS. 12-13 should not be construed as limiting the scope of the invention.

FIG. 12 is a flow chart of a method for control of an appliance by a canal hearing device, according to some examples. In step 1202, a switch positioned on a lateral end of the canal hearing device is activated. The lateral end may include wireless electronics and a wireless antenna for communicatively coupling the canal hearing device to an external appliance. The canal hearing device may further include a medial end including a speaker.
